Do you know my great grandfather was American and came to Canada when he was 17 to join the Northwest Mounted Police (now the RCMP or Royal Canadian Mounted Police, though they only use horses for shows now).?

(Sorry, had to go for dinner)
Do you know that I never met him? But I have researched him for our family tree and have read a lot of stories about him. Do you know I would have loved to have known him?
